TECHNICAL FIELD

The disclosure relates to, but is not limited to, an information sendingand receiving method and device, a storage medium and a processor.

BACKGROUND

A high band with an ultra-wide bandwidth (that is, millimeter-wavecommunication) is a significant development direction of mobilecommunication in the future. Particularly, when spectrum resources andphysical networks are accessed in large numbers, an advantage of themillimeter-wave becomes increasingly attractive. Many standardorganizations, such as the Institute of Electrical and ElectronicsEngineers (IEEE), and the 3rd-Generation Partnership Project (3GPP),have embarked on the development of corresponding standardization work.For example, in the 3GPP standardization group, high-band communicationis an important innovative point of a 5G New Radio Access Technology(New RAT) because of the large bandwidth it offers.

However, the high-band communication faces the challenge of linkattenuation or link decay. The loss on a propagation path is especiallylarge when the air (particularly oxygen) has a higher absorption rate.Accordingly, rain and other factors that affect the absorption rateinfluence the high-band communication. In the face of these challenges,a high-band communication system can achieve high antenna gain andanti-jamming signal transmission loss through multi-antenna arrays andbeamforming solutions to ensure link margin and can improvecommunication robustness by using the characteristics of high band-shortwavelength and is easy to integrate antennas, etc.

During an antenna weight training process, a high-band transceiver sendsa training guide (also known as pre-coded, beam), and receives thechannel, and performs channel estimation. Then, the receiver sends backa channel state information to the transceiver that sent the trainingguide, so that the transceiver finds multiple groups of receiverantennas with weight pairs for multi-path data transmission from theoptional transceivers, the antenna weight pairs facilitating to improvethe overall spectrum efficiency.

This embodiment provides a method for feeding back channel-relatedinformation, which focuses on that a user in a trigger conditionactively feeds back channel quality information (equivalent to theinformation related to the reference signal in the above embodiment),and is applied to a first communication node (that is, a UE side). Themethod includes: a first signal is generated according to a firsttrigger threshold for K elements in a beam-related parameter set,wherein the K is an integer greater than or equal to 1; and the firstsignal is sent to the first communication node. This process may also bereferred to as beam recovery or active beam reporting of the user.

FIG. 10 is a flowchart schematic diagram for channel quality feedbackbased on a trigger condition provided by an embodiment of thedisclosure. An eNB configures a periodic CSI-RS for detecting beamfailure. In a case where the BLER performance associated with the CSI-RSis greater than or equal to a determination threshold, a UE determinesbeam failure detection. Additionally, the eNB configures an SS Block(SSB) and a periodic CSI-RS resource to form first beam link quality. Ina case where channel quality (such as a BLER or an RSRP) associated withone CSI-RS resource in the first beam link quality triggers thethreshold, the UE declares to discover a new candidate beam.

When all second beam link qualities (CSI-RS) trigger the threshold andone first beam link quality (such as the CSI-RS, or the SS block)triggers the threshold, a user may start a first signal sending process,that is, the first signal, like beam recovery request signal, may besent on a corresponding uplink resource.

In an embodiment, based on a restriction condition for sending the firstsignal, with a view to a case where a trigger condition is met, or thereis beam failure, the user may select a newly available beam from acandidate beam set (that is, configured optional beams, the first beamlinks). However, it is necessary to restrict a behavior of the userside, so that the UE may be guaranteed to quickly execute the beamrecovery process under an effective time restriction and number-of-timesrestriction, thus assuring the beam recovery performance, and preventingthat the beam recovery time is too long and the UE waits for aneffective beam for a long time.

The first signal includes one or a combination of the followingconfiguration information: a first signal number-of-times threshold, anda cumulative time threshold.

In an embodiment, the configuration restriction condition is as follows:in a case where the configuration information is the first signalnumber-of-times threshold when the number of times for the first signalexceeds the first signal number-of-times threshold, the secondcommunication node stops sending the first signal; or, in a case wherethe configuration information is the cumulative time threshold when anassociated timing unit exceeds the cumulative time threshold, the secondcommunication node stops sending the first signal; or, in a case wherethe configuration information is the cumulative time threshold and thefirst signal number-of-times threshold when the associated timing unitexceeds the cumulative time threshold, and/or, the number of times forthe first signal exceeds the first signal number-of-times threshold, thesecond communication node stops sending the first signal.

In addition, considering that the first signal cannot be senteffectively (that is, in case of the failure of the beam recovery), atleast one of the following is further included: after the number oftimes and/or the cumulative time that the second communication nodesends the first signal to the first communication node exceed athreshold, the second communication node notifies a high layer of type-Ainformation; and within Y time units after the number of times and/orthe cumulative time that the second communication node sends the firstsignal to the first communication node exceed the threshold, the secondcommunication node notifies the high layer of the type-A information,wherein the Y is an integer greater than or equal to 0. The type-Ainformation represents a trigger condition for the failure of the beamrecovery and/or the failure of the wireless link.

It is to be noted that, regarding restriction on a start point forcalculating the cumulative time, for the restriction for sending thefirst signal, the start point of the cumulative time may be one of thefollowing: 1) a moment when the failure of the associated link or beamis detected, or a marking moment of a time window associated with themoment when the failure of the associated link or beam is detected; 2) amoment when a beam failure detection result triggers the threshold, or amarking moment of a time window associated with the moment when the beamfailure detection result triggers the threshold; 3) a moment for sendingthe first signal for a first time, or a marking moment of a time windowassociated with the moment for sending the first signal for the firsttime; 4) a moment when the second communication node configures anuplink resource for bearing the first signal, or a marking moment of atime window associated with the moment when the second communicationnode configures the uplink resource for bearing the first signal islocated; 5) a moment for sending the reference signal index borne on thefirst signal, or a marking moment of a time window associated with themoment for sending the reference signal index borne on the first signal;6) a moment when the PUCCH is used for a first time to send the firstsignal, or a marking moment of a time window associated with the momentwhen the PUCCH is used for the first time to send the first signal; and7) a moment when the PRACH is used for a first time to send the firstsignal, or a marking moment of a time window associated with the momentwhen the PRACH is used for the first time to send the first signal. Themarking time of the time window refers to a start moment of the timewindow, or a middle moment, or an end moment.

In an embodiment, the number of sending times for the first signalincludes at least one of the following: 1) the number of sending timesfor the first signal refers to the number of times for sending the firstsignal by using a PUCCH resource; 2) the number of sending times for thefirst signal refers to the number of times the first signal is sent byusing a PRACH resource; and 3) the number of sending times for the firstsignal refers to a sum of the number of times for sending the firstsignal by using the PRACH and the number of times for sending the firstsignal by using the PUCCH resource.

In an embodiment, based on the method for configuring the PRACH resourceassociated with the first signal, as the first signal involves in theuse of the PRACH, and the PRACH resource is configured in advance in aninitial access stage, the configuration of the PRACH resource forsending the first signal should be limited for the UE. Additionally, thePRACH is only associated with the SS block during the initial accessstage, but for the first signal, the PRACH may be associated with theCSI-RS, the SS block, or the CSI-RS and the SS block. In this sense,when the eNB is configured with the CSI-RS and the SS block, certainassumptions of the UE side need to be met, so that the UE supportsrelevant measurement and reporting of the first signal.

The restriction on the allocation of the PRACH resource supports atleast one of the following: in a case where a downlink reference signalassociated with N PRACHs meets a channel pattern assumption, the N PRACHresources are allocated in the same time-domain unit, or support FDM.The first communication node does not expect that when the associateddownlink reference signal meets the channel pattern assumption, thePRACHs are allocated in different time-domain units. The time-domainunit includes a time slot, a subframe, a symbol, or a symbol set. In anembodiment, the downlink reference signal includes one or a combinationof the following: the CSI-RS and the SS block.

The PRACH resource has the following patterns, including at least one ofthe following: a time-domain position of the PRACH resource of the firstsignal is determined according to a time-domain position of a PRACH thatis accessed initially and corresponding to an SS block associated withthe PRACH of the first signal, wherein the time-domain position of thePRACH that is accessed initially is implemented by configuration signalof the PRACH that is accessed initially and sent by the firstcommunication node to the second communication node. The time-domainposition is time-domain offset information.

A PRACH resource of the first signal is determined according to a PRACHresource that is accessed initially and corresponding to the SS blockassociated with the PRACH of the first signal. A time-domain position ofthe PRACH resource of the first signal is determined according to atime-domain position of a PRACH that is accessed initially andcorresponding to an SS block, meeting the same channel patternassumption, of a CSI-RS associated with the PRACH of the first signal.The PRACH resource of the first signal is determined according to aPRACH resource that is accessed initially and corresponding to an SSblock, meeting the same channel pattern assumption, of the CSI-RSassociated with the PRACH of the first signal.

The first communication node does not expect that a time-domain offsetof the PRACH that is accessed initially and corresponding to the SSblock associated with the PRACH of the first signal is different from atime-domain offset of the PRACH resource of the first signal; or, thefirst communication node does not expect that a time-frequency offset ofthe PRACH that is accessed initially and corresponding to the SS blockassociated with the PRACH of the first signal is different from atime-frequency offset of the PRACH resource of the first signal.

A reference of the time-frequency offset may be an OFDM symbol (or afirst Resource Element (RE) of the OFDM symbol) where a first SS blockof each SS block burst is located or the first RE of a Bandwidth Part(BWP) where the first SS block is located.

The first communication node does not expect that a time-domain offsetof the PRACH that is accessed initially and corresponding to the SSblock, meeting the same channel pattern assumption, of the CSI-RSassociated with the PRACH of the first signal is different from thetime-domain offset of the PRACH resource of the first signal; or, thefirst communication node does not expect that a time-frequency offset ofthe PRACH that is accessed initially and corresponding to the SS block,meeting the same channel pattern assumption, of the CSI-RS associatedwith the PRACH of the first signal, is different from the time-frequencyoffset of the PRACH resource of the first signal.

In an embodiment, a part of sets are selected from pre-configured setsfor PRACH-beam recovery, with the pattern including at least one or acombination of the following: the second communication node sends secondsignal to the first communication node, to indicate V PRACH resources inconfigured or pre-defined PRACH resources for indicating a time-domainand/or frequency domain position of the PRACH resource associated withthe first signal; the second communication node sends third signal tothe first communication node, to indicate T CSI-RS resources and/or SSblocks from configured or pre-defined CSI-RS resources and/or SS blocksfor correspondence with the PRACH resource of the first signal; and thePRACH associated with the first signal uses the PRACH resource that isaccessed initially and corresponding to the SS block associated with thePRACH of the first signal; or, the first communication node has thefollowing default configurations; the PRACH associated with the firstsignal uses the PRACH resource that is accessed initially andcorresponding to the SS block associated with the PRACH of the firstsignal; and the PRACH associated with the first signal uses the PRACHresource that is accessed initially and corresponding to the SS block,meeting the same channel pattern assumption, of the CSI-RS associatedwith the PRACH of the first signal; or the first communication node hasthe following default configurations; the PRACH associated with thefirst signal uses the PRACH resource that is accessed initially andcorresponding to the SS block, meeting the same channel patternassumption, of the CSI-RS associated with the PRACH of the first signal.The V and the T are an integer greater than or equal to 1. In anembodiment, selecting a special set from existing sets may use a bitmapmethod. In a case where a bit in the bitmap is assigned as a specialvalue (such as 1), it is showed that the PRACH resource associated withthe bit is indicated.

For example, the eNB is configured with 16 periodic CSI-RS resources, inwhich 4 periodic CSI-RS resources serve a current transmission beam(that is, the second beam link, serving beam), and the rest 12 periodicCSI-RS resources are used to discover a new beam (that is, the firstbeam link, new candidate beam identification). The bitmap is used toselect 4 resources from the configured 16 periodic CSI-RS resources,that is, the bitmap of 16′b1111_0000_0000_0000 represents the secondbeam link; and additionally, 12 resources in the 16 periodic CSI-RSresources, that is, the bit map of 16′b0000_1111_1111_1111, is used toselect the configured additional 12 resources.

In a case where the CSI-RS and the SS block are in a one-to-onerelationship, the PRACH resource associated with the SS blockcorresponding to the bitmap of 16′b0000_1111_1111_1111 is configured toserve as an exclusive reporting resource of the first signal.

In a case where every four CSI-RSs are associated with one SS block, thePRACH time-frequency resource associated with the SS block associatesthe four CSI-RSs. Nevertheless, each CSI-RS is configured or isdistinguished by using 4 different sequences according to a pre-definedrule.

Additionally, in a case where multiple CSI-RSs and SS blocks of the QCLare supported to be configured, the PRACH associated with the SS blocksmay serve as a reference; and then, the configuration of the CSI-RSs andthe SS blocks meeting a QCL relationship is implemented at a specialfrequency domain step value. Specifically, the second communication nodeconfigures the frequency domain step value to the first communicationnode to indicate a frequency domain interval between PRACHs in the sametime-domain unit. The multiple CSI-RSs of the QCL use the same sequence.The CSI-RS resources are distinguished by the eNB via differentfrequency domain resources.

FIG. 11 is a schematic diagram of a method for associating a referencesignal and a PRACH resource provided by an embodiment of the disclosure.It is assumed that the system configures 4 CSI-RS resources to serve asthe second beam links (that is, new candidate beam identification), andthe four CSI-RS resources meet the channel pattern assumption (such asspatial QCL) together with one SS block. According to the method forconfiguring the SS block and the PRACH during initial access, the CSI-RSresource is in one-to-one mapping with the PRACH having the sametime-domain resource but a different frequency domain resource. Thefirst CSI-RS is directly associated with the PRACH associated with theSS block, and the other CSI-RSs are sequentially associated with PRACHsat other frequency domain positions. In an embodiment, if only oneCSI-RS is configured in the SS block, the PRACH that is defaulted to beassociated and meeting the correspondence relationship is PRACH-0 in thefigure.

In addition, both the PUCCH and the PRACH may be used to bear the firstsignal, may share some same configurations, or use the sameconfiguration or mode and include at least one or a combination of thefollowing: a duration of a response window of the second communicationnode; a time offset between the response window of the secondcommunication node and time for sending the first signal to the secondcommunication node; a CORESET resource; and a search space.

In an embodiment, the first communication node (UE) feeds back, based ona criterion, a behavior smaller than a feedback limit configured by theeNB.

By receiving the reference signal sent by the second communication node(that is, the eNB side), the first communication node (that is, the UEside) determines a reference signal related index, an RSRP, or thereference signal related index and the RSRP. In an embodiment, thereference signal related index, or the RSRP, or the reference signalrelated index and the RSRP are reported to the second communicationnode. It is to be noted that the reference signal related index is usedto indicate sending beam information, and thus the report may bereferred to as beam reporting. By indicating the reference signalresource such as the CSI-RS resource or the SS block, indication andreporting of a sending beam or an air filter at the sending end areimplemented (for example, an effective beam index is indicated).

It is to be noted that the reference signal received power refers to anRSRP. For the ease of discussion, the RSRP is used below to replace thereference signal received power for description.

During beam reporting, for the feedback number N of the reference signalrelated indexes configured by the eNB and the number of the reportedreference signal related indexes fed back by the UE side, the M issmaller than or equal to the N, and the M and the N are an integergreater than or equal to 0. In an embodiment, the feedback criterion forthe reference signal related index includes at least one or acombination of the following: 1) a difference value of an RSRPassociated with the reference signal relative to a maximum RSRP issmaller than or equal to a threshold T-1. In an embodiment, the T-1 isconfigured by the second communication node, or determined by avariation range of a differential RSRP, or pre-defined in a standard. 2)A difference value of the RSRP associated with the reference signalrelative to a maximum RSRP in a group where the reference signal islocated or a difference value relative to an RSRP of a special referencesignal is smaller than or equal to a threshold T-2. In an embodiment,the T-2 is configured by the second communication node, or determined bya variation range of a differential RSRP, or pre-defined in a standard.3) A difference value of the RSRP associated with the reference signalrelative to a reference power of a different RSRP is smaller than orequal to T-3. In an embodiment, the T-3 is configured by the secondcommunication node, or determined by a variation range of a differentialRSRP, or pre-defined in a standard. 4) The RSRP associated with thereference signal is greater than or equal to a threshold T-4. In anembodiment, the T-4 is configured by the second communication node, ordetermined by a variation range of a differential RSRP, or pre-definedin a standard.

For example, the eNB side configures 8 CSI-RS resources for beamtraining and then configures relevant resources for the UE side to feedback the beam reporting, in which 4 beam resources are allowed to be fedback. With channel measurement on 8 CSI resources, the UE side obtainscorresponding RSRP results, as shown in Table 1, wherein the CRI isCSI-RS resource indication.

TABLE 1 CRI-0 −79 dBm CRI-1 −60 dBm CRI-2 −96 dBm CRI-3 −74 dBm CRI-4−95 dBm CRI-5 −130 dBm  CRI-6 −110 dBm  CRI-7 −86 dBm

According to the restriction for feeding back the 4 beam resources,{CRI-0, CRI-1, CRI-3, CRI-7}, and corresponding RSRP measurement resultsmay be fed back to the eNB side. For example:

Case 1: in a case where the eNB side configures a minimum feedbackthreshold, that is, −85 dB, then CRI-7 cannot meet the thresholdrestriction, and the user side only feeds back the followinginformation: {[CRI-0, −79 dBm], [CRI-1, −60 dBm], [CRI-3, −74 dBm]}.

Case 2: the UE side uses 4-bit for differential reporting, each bit hasa step of −1 dB, the maximum RSRP is reported based on an absolute valueand others are reported based on relative value. Specifically, thefollowing differential table is provided, as shown in Table 2.

TABLE 2 4′b0000 −0 dBm 4′b0001 −1 dBm 4′b0010 −2 dBm . . . 4′b1111 −15dBm

When the determination criterion “the difference value of the RSRPassociated with the reference signal relative to the maximum RSRP” isexecuted, and it is determined that the threshold is based on 15 dB ofthe variation range of the differential table, since the maximum RSRPvalue is 60 dBm at the UE side, only −75 dBm and above beams are fedback with the report of {[CRI-1, −60 dBm], [CRI-3, −14 dBm (i.e.,4′b1110)]}, and other beams do not meet the criterion.

Case 3: the UE side uses 4-bit for differential reporting, each bit hasa step of −1 dB, the maximum RSRP is an absolute value and other reportsare differential reporting based on an RSRP that is nearest to thereceiving power and may be reported. At the UE side, the maximum RSRPvalue is −60 dBm, so [CRI-3, −14 dBm (i.e., 4′b1110)] is fed backdifferentially; then, [CRI-0, −5 dBm (i.e., 4′b0101)] is differentiallyreported based on −74 dBm; and thereafter, [CRI-7, −7 dBm (i.e.,4′b0111)] is differentially reported based on −79 dBm. In this case, theUE side has the following report information: {{[CRI-1, −60 dBm],[CRI-3, −14 dBm (i.e., 4′b1110)], [CRI-0, −5 dBm (i.e., 4′b0101)],[CRI-7, −7 dBm (i.e., 4′b0111)]}.

It is to be noted that in a case where the reference RSRP measured valuedoes not comply with the report values in actual differential reporting,the reference RSRP in the report values should serve as a reference fordifferential reporting.

In an embodiment, the operation that the first communication node (UE)feeds back the beam reporting is divided into two different parts forfeeding back distinctively.

For the beam reporting, different contents are varied in reportingurgency and priority. Therefore, it is recommended that a reportingcontent is divided into two or more stages, and each stage has acorresponding information content and modulation coding mode, thusimplementing the requirement on the flexibility of the beam reporting.

The beam reporting content is composed of the first information andsecond information, wherein the first information is composed of atleast one or a combination of the following information: the number ofthe reference signal related indexes; the number of the reference signalgroups; a group index of the reference signal group; a maximum RSRPvalue in the group; a maximum RSRP value; an absolute RSRP indifferential reporting; a reference signal related index associated withthe absolute RSRP in the differential reporting; a reference signalrelated index specified by the second communication node; and an RSRPvalue of a reference signal specified by the second communication node.

Additionally, the second information is composed of the reference signalrelated index and/or the RSRP. In an embodiment, the reference signalgroup, which is also referred to as a beam group, has a criterionincluding at least one or a combination of the following: in thereference signal group, different reference signals cannot be receivedsimultaneously; in the reference signal group, different referencesignals can be received simultaneously; in the reference signal group,W1 different reference signals can be received simultaneously; betweenthe reference signal groups, different reference signals cannot bereceived simultaneously; between the reference signal groups, differentreference signals can be received simultaneously; and between thereference signal groups, W2 different reference signals can be receivedsimultaneously. The W1 and the W2 are a positive integer greater than orequal to 1. In an embodiment, the W1 and the W2 need to be notified tothe eNB by the UE, or are determined by the eNB according to acapability of the UE.

In an embodiment, the RSRP is a relative receiving power in the secondinformation; or, the reference signal related index is indicated byusing a bitmap in the second information; or, a modulation coding mannerof the first information is different from a modulation coding manner ofthe second information.

In an embodiment, the first information and the second information haveone of the following configurations: the first information and thesecond information are fed back by using the PUCCH resource; the firstinformation and the second information are fed back by using the PUSCHresource; and the first information is fed back by using the PUCCHresource, and the second information is fed back by using the PUSCHresource.

In a case where the first information is fed back by using the PUCCHresource, and the second information is fed back by using the PUSCHresource, the second communication node cannot configure thedifferential RSRP for feedback; or, the second communication node canconfigure the differential RSRP for feedback; or, the firstcommunication node does not expect that the second communication nodeconfigures the differential RSRP for feedback; or, the firstcommunication node expects that the second communication node configuresan absolute RSRP for feedback.

FIG. 12 is a first schematic diagram of a beam reporting feedback methodprovided by an embodiment of the disclosure. According to the RSRPmeasurement result of the UE side that is described in Table 1, the UEdivides a feedback content into two parts, namely, a first reportingpart and a second reporting part, wherein the first reporting partincludes first information, and the second reporting part includessecond information. The first information bears a reference signal indexof the strongest RSRP and an RSRP at this index. The second informationbears other reference signal indexes and RSRPs at these indexes. In anembodiment, the second information is reported by using a differentialRSRP; and the first information is reported by using an absolute RSRP,with a report result serving as a reference value or one of thereference values for the differential RSRP in a second report.

FIG. 13 is a second schematic diagram of a beam reporting feedbackmethod provided by an embodiment of the disclosure. According to theRSRP measurement result of the UE side that is described in Table 1, andaccording to the grouping criterion that “in the reference signal group,different reference signals can be received simultaneously, and betweenthe reference signal groups, different reference signals cannot bereceived simultaneously”, specifically, according to the criterion, theUE divides {CRI-1, CRI-3} into a first beam group and {CRI-0, CRI-7}into a second beam group. Different reference signals may be receivedsimultaneously in the group, for example, by means of one air receivingfilter or two air receiving filters.

In an embodiment, the UE divides a feedback content into two parts,namely, a first reporting part and a second reporting part. The firstreporting part includes first information, and the second reporting partincludes second information. The first information bears CRI informationof a strongest RSRP and the RSRP thereof in the first beam group(equivalent to the reference signal group) and the second beam group.The second information bears other CRI information in the groups anddifferent RSRP reports that take absolute RSRPs in the groups asreferences.

In an embodiment, the differential RSRPs in the beam groups are fedback.

In the reference signal group or the beam group, in order to save thefeedback overhead, it is necessary to introduce a differential RSRPfeedback method. In an embodiment, the method needs to group clearly;and particularly in multiple groups, there is a need for determinationof the reference RSRP and a relationship problem between the groups.Specifically, at least one or a combination of the following isincluded:

a) In the reference signal group, X reference signals feed back thedifferential RSRP.

b) Y reference signals are selected from each group in D referencesignal groups, and the reference signals feed back the differentialRSRP.

c) In each reference signal group and between the reference signalgroups, J reference signals feed back the differential RSRP.

The X, the Y, the D, and the J are positive integers greater than orequal to 1.

a) When X reference signals feed back the differential RSRP in thereference signal group, the reference power of the differential RSRP maybe at least one of the following: an RSRP of a special reference signalin the group; an RSRP of a special reference signal out of the group; areference value reported by a differential RSRP configured by the eNB;and an RSRP of a special reference signal in the X reference signals.

In an embodiment, the special reference signal is equivalent to thespecified reference signal in the above embodiment.

Case b) when Y reference signals are selected from each group in Dreference signal groups, and the reference signals feed back thedifferential RSRP, the reference power of the differential RSRP may beat least one of the following: an RSRP of a special reference signal inthe D reference signal groups; an RSRP of a special reference signal outof the D reference signal groups; a reference value reported by an RSRPconfigured by the eNB; and an RSRP of a special reference signal in theY reference signals of the D reference signal groups.

Case c) when J reference signals feed back the differential RSRP in eachreference signal group and between the reference signal groups:

The reference power of the differential RSRP may be at least one of thefollowing: an RSRP of a special reference signal in the J referencesignals; a reference value reported by a differential RSRP configured bythe eNB; and an RSRP of a special reference signal out of the Jreference signals.

For the case a) and the case c), the special reference signal is areference signal having a maximum or minimum RSRP in internal referencesignals of the group; or, the special reference signal is a referencesignal having a maximum or minimum RSRP in all reference signals.

Besides, for the feedback of the differential RSRP, the step value ofthe differential reporting is also very important except for thereference value. The step value of the differential RSRP may beconfigured via at least one or a combination of the following: the stepvalue is determined according to a pre-defined step value; the stepvalue is determined according to a reference power of the differentialRSRP; and the step value is determined according to the reference powerof the differential RSRP and a threshold configured by the secondcommunication node.

A condition for executing the feedback of the differential RSRP includesat least one of the following: 1) a reference signal type; and 2) thenumber of reference signals. For example, for the feedbacksimultaneously supporting the CSI-RS and the SS block, it may beappropriate that only the SS block supports the differential reportingand the SS block does not support the differential reporting, or, theCSI-RS and the SS block may be respectively subjected to thedifferential reporting, which means that when the CSI-RS and the SSblock are subjected to the differential reporting, the reference valueof the RSRP may be irrelevant.

For example, the eNB side configures 6 CSI-RS resources for beamtraining, and then configures relevant resources for the UE side to feedback the beam reporting, in which 2 beam resources are allowed to be fedback provided that the 2 beam resources may be received simultaneously,that is, one beam group is fed back. With channel measurement on 6 CSIresources, the UE side obtains corresponding RSRP results, as shown inTable 3. Meanwhile, CRI-0 and CRI-5 may be received simultaneously, andCRI-1, CRI-2, CRI-3 and CRI-4 may be received simultaneously.

TABLE 3 CRI-0 −79 dBm CRI-1 −60 dBm CRI-2 −66 dBm CRI-3 −74 dBm CRI-4−95 dBm CRI-5 −100 dBm 

The UE side selects {CRI-1 and CRI-2} for beam grouping and reporting.At this moment, the CRI-1 serves as a reference signal index with amaximum RSRP in the group, and the RSRP value {−60 dBm} uses absolute ornon-differential RSRP reporting; and the RSRP value [−66 dBm] of theCRI-2 uses relative RSRP reporting. According to a differential steprelationship described in Table 2, a relevant report of the CRI-2 is[CRI-2, −6 dBm (i.e., 4′b0110)]. Therefore, the report has the followingcontent information: {[CRI-1, −60 dBm], [CRI-2, −6 dBm (i.e.,4′b0110)]}.

In a case where the eNB configures that the UE feeds back 4 beamresources and the 4 beam resources meet the assumption that they may bereceived simultaneously, one beam group is fed back. Meanwhile, the eNBconfigures that a lower limit for beam selection is −90 dBm. When thedifferential step is configured as a difference value between themaximum RSRP in the group and the lower limit configured by the eNB,4-bit may be used in total and a formula for calculating the step valueis as follows:Step value={Max of RSRP−Threshold}/(2{circumflex over ( )}n−1)

The Step value denotes the step value, the Max of RSRP denotes themaximum RSRP or the maximum RSRP in the group, or the reference RSRPvalue, the Threshold denotes the threshold configured by the eNB, andthe n denotes the number of bits for the differential reporting. Bybringing into the formula, the step value is (−60−(−90))/15=2 dB.Additionally, considering that the CRI-4 does not meet the thresholdrequirement, the UE side only reports 3 pieces of beam information (thatis, 3 reference beam indexes). The specific reporting information is asfollows: {[CRI-1, −60 dBm], [CRI-2, −6 dBm (i.e., 4′b0011)]} {[CRI-3,−14 dBm (i.e., 4′b0111)]}.

In an embodiment, the second communication node (gNB) indicates the beamfeedback.

The reference signals configured by the eNB and used for beam trainingmay have different priorities. This is because some reference signalsmay be used to support the current serving beam or optional beam set,and other reference signals may be merely used for beam training of thegeneral sensor to discover a new potential beam. In this case, the eNBmay specify a special beam, and require the UE to report certainly orreport preferentially.

For the reference signal sent by the second communication node (that is,the eNB), the second communication node configures a report mode of thereference signal. The report mode includes at least one or a combinationof the following: a first report mode, and a second report mode, whereinthe first report mode has a higher priority than the second report mode(or, requires that a beam report must be fed back); or, a threshold ofthe first report mode is smaller than a threshold of the second reportmode. Specifically, the reference signal related index and/or the RSRPof the associated reference signal is reported in the first report mode;and the reference signal related index and/or the RSRP of the associatedreference signal may be reported or may not be repeated in the secondreport mode.

In an embodiment, as the reference signal must be fed back in the firstreport mode, the UE may not feed back corresponding index informationbut feeds back a corresponding relationship in an implicit method, forexample, the UE indicates the reference signal index via a sequenceposition of the RSRP.

Concerning how to support differential RSRP reporting, the first reportmode and the second report mode are respectively subjected to thedifferential RSRP feedback; or, the absolute RSRP is used for feedbackin the first report mode, and the differential RSRP is used for feedbackin the second report mode; or, the absolute RSRP is used for feedback inthe second report mode, and the differential RSRP is used for feedbackin the first report mode. In an embodiment, the first report mode andthe second report mode are respectively subjected to the differentialRSRP feedback, or have different step values in differential reporting,or respectively configure the step value.

In an embodiment, a configuration range of the eNB is limited accordingto a capability of the UE.

According to different capabilities of the UE, a parameter that may beconfigured by the eNB side is effectively limited, so that the overheadfor configuring signal may be saved, the unnecessary expense for feedingback a resource during channel quality feedback is also saved, and aconfiguration behavior that cannot be supported by the user side isprevented.

The embodiments of the disclosure provide a method for configuringinformation, which is applied to a second communication node andincludes at least one of the following.

The second communication node determines a configuration restrictionaccording to a capability of a first communication node, including atleast one or a combination of the following: a PUCCH, a PRACH, a beamrecovery PRACH, a first signal number-of-times threshold, and acumulative time threshold.

In an embodiment, the capability of the first communication nodeinvolves at least one or a combination of the following: support forbeam correspondence; support for non-beam correspondence; support forpartial beam correspondence; and an antenna parameter.
